{"version":"1.0","type":"rich","title":"Svelte + D3: Radial","description":"This radial chart displays daily global surface temperatures from 1940 to 2024, with each year drawn as a single circular path. The visualization highlights 2023 and 2024 in distinct colors, while older years appear as faint white rings. Using d3.lineRadial with a curveCatmullRom, the code maps day-of-year to angle and temperature values to radius via d3.scaleLinear. Data is loaded from a CSV using d3.csv with autoType, grouped by year with d3.groups, and rendered as SVG paths. The background uses a dark radial gradient, with an opacity scale differentiating historical from recent years.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ee94134a986c4834a6f3af120105ee3a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
